Grey, brown or green? A guide to sunglass lens tints

Start with the thing most people get backwards: a dark lens is not a protective lens. UV protection comes from the lens material and its UV treatment, not from how dark it looks. A cheap, very dark lens with no UV filtering is worse than no sunglasses at all, because the darkness opens your pupil and lets more unfiltered UV in.

Confirm UV400 first. Then choose a tint for how you want to see.

Grey

The neutral choice. Grey reduces brightness across the visible spectrum fairly evenly, so colours look close to true — just dimmer. Nothing gets warmed or pushed.

Best for: general daily wear, driving, the beach, anyone who wants the world to look the way it looks. If you are buying one pair and cannot decide, buy grey.

Brown and amber

Brown filters more of the short-wavelength blue end of the spectrum. That reduces the haze of scattered light and increases apparent contrast, especially against green and blue backgrounds. The trade-off is a warm colour shift — everything looks slightly gold.

Best for: overcast days, golf, fishing, hiking, anyone who wants depth and definition more than colour accuracy. Also a common preference for people who find grey lenses flat.

Green

The middle ground. Green filters some blue like brown does, but keeps colour rendering closer to neutral than brown. It has been a classic sunglass tint for a century for a reason.

Best for: long days in bright sun where you want contrast but cannot accept a heavy colour cast. A good everyday compromise.

Mirror coatings

A mirror finish reflects some light away before it enters the lens, so less total light reaches your eye. It is useful at very high brightness — open water, sand, altitude. It also scratches more visibly than a plain lens, so treat a mirrored pair carefully.

Mirroring is a coating on top of a tint, not a replacement for UV protection.

What about the very light fashion tints?

Pale pinks, light blues and gradients are style choices, not sun protection. They are fine for indoors, photos and mild light. They will not carry you through a midday walk in Philippine sun. If the frame is a style buy, that is a completely legitimate reason to own it — just do not ask it to do a job it is not built for.

Tint or polarisation?

They solve different problems. A tint reduces overall brightness. Polarisation removes glare reflected off flat surfaces — wet roads after an afternoon downpour, car bonnets, the sea.

For most Filipino conditions, polarisation is the bigger upgrade. Two caveats worth knowing before you commit: polarised lenses can make some phone and dashboard displays look dark at certain angles, and they are for daytime use only.

A short buying checklist

• UV400 confirmed — non-negotiable
• Large enough lens, or a wrap, to cover the skin around the eyes
• A frame that actually holds position when you sweat
• Grey for neutrality, brown for contrast, green for both
• Polarised if you drive, ride or spend time on the water

Come and compare them in daylight

Visit a Vision Express store and look through the tints side by side — the difference between grey, brown and green is obvious in your hand and impossible to judge from a product photo.

If you wear a prescription, book a Vision7 eye test while you are there. The seven-step exam confirms your current grade before the sun lenses are cut, so you are not paying to put an out-of-date prescription into a new frame.

For prescription sunglasses, ask for Shamir Opulens Exact ordered polarised at the counter. Made to your exact measurements and polarised, it kills the reflected glare off wet asphalt and bright water that a plain tint just dims.

If you would rather have one pair that adapts between indoors and out instead of a dedicated sun pair, ask for Essilor Transitions Classic HMC 1.56 — clear inside, darkening in sunlight, ready in one to two days.

Every pair includes free lifetime ultrasonic cleaning, free lifetime custom fitting and adjustment, and a 1-year warranty on eyeglasses and sunglasses.
